VAPOR-STOVE.

This invention relates to kerosene burning stoves, and the primaryobject of my ln'vention'is to provlde a novel burner wlnch will permitof kerosene being utilized as a fuel, and novel means is employed forvaporizing the kerosene so that it may commingle with air and readilyburn at a burner. v

A furtherobject of my invention is to provide a gas generating apparatusthat may be attached to various types of stoves,

for generating a vapor which will burn with a flame of high calorlcvalue and the construction of the generator is such that it may besafely used. c

A still further object of my invention is to provide a stove burner withmeans for supplying fuel thereto, wherein the parts are constructed witha view of reducing the cost of manufacture and at the same time retainthose features by which durability,

- simplicity of construction, and ease of assembling are secured. WVithsuch ends in View, :my invention resides in the novel construction,combination and'arrangement of parts to be hereinafter specificallydescribed and then claimed.

Reference will now be hadto the drawing, wherein- Figure 1 is a plan ofa range provided with burners in accordance with my invention; v r

Fig. 2 is a longitudinal sectional view of one of the burners, on alarge scale and taken on or about line 2-2 of Fig. 1;

Fig. 3 is a vertical sectional view ofa heating stove in accordance withmy invention;

*ig. 4 is an enlarged sectional view of the burner of the stove;

Fig. 6 is an enlarged cross sectional view 7 of the fuel tank;

Fig. 8 is a side elevation. of a portion of the needle valve, and

Fig. 9 is a plan of a detached flame deflector that may be used on theburner.

Reference will first be had to Figs. 1 and 2 showing the manner of usingburners as a part of a gas plate or range 1 which has a plurality ofgrids 2. Below each grid is a burner in communication with a supply pipe3 connected by a coil 4 to a fuel tank 5 containing kerosene or similarfuel. The tank 5 may be supported conveniently at the end of the range 1vby straps 5 encircling the fuel tank and connected to the end of arange and said tank has one end thereof connected by a pipe 6 toamanually operated air pump 7 mounted on the tank 5, said pump being usedto force air into the tank 5 so that the contents thereof will benormally under pressure suiiicient to force the kerosene laden air intothe supply pipe 3 and to the burners connected thereto.

The tank 5 has a filling opening 8 which is normally closed by a cap orother closure member and on top of said tank is a conventional form ofsafety valve 9 which may be adjusted so that an excessive quantity ofair within the tank 5 may escape to the atmosphere and thus prevent thetank 5 from being overcharged. Adjacent the tank is also a shut offvalve 10 for the coil at and this shut off valve permits of all of theburners being rendered inactive and the fuel retained within the tank 5independent of any other valve.

Considering one of the burners, as shown in Fig. 2, a T connection orbody 11 is employed and provided with reduced ends 12 and 13, the formerforming an annular shoulder 1% on which may be mounted a nipple is atapering outlet port 18 for a fine needle 18 of a needle valve'19disposed longitudinally of the T body 11 and entered therein through thereduced end 13 of said T body which is normally closed by a cab 20. Thelower end of the needle valve 19' is comparatively flat so that its sideedges may slide in opposed grooves 11 provided therefor in the reducedend 13 of the T body 11 and prevent rotative movement of theneedlevalve. The flat portion of the needle valve is slotted, as at 21, andone of the walls of the slot provided with a rack 22 for a pinion 23which extends into'the slot 21. The pinion 23 is on the inner end of arod 24 which has its inner end journaled in a wall of the T body 11 andits outer end extending through a pipe 25 connected to the T body l land provided with an angle connection 26 having a stufling box 27through which the rod 24 extends, said rod having a suitable hand wheel28 so that the rod may be rotated to adjust the needle valve 19 throughthe medium of the rack .22 V and the pinion 23. The rod 24 has a reducedend portion 24? into which extends a set V screw 25*, carried by theangle connection '26,'and this set screw prevents longitudinaldisplacement of the rod 24 and permits of said rod being removed. Theangle connection 26 is included in the fuel supply pipe 3 andadjacenteach angle connection of said pipe there is a-shut off valve 29, whichcontrols the supply of fuel from the pipe3 to.

the angle connection 26 and thus permits of the burners of the range 1being used independent of each other.

Reference will now'be had to Figs. 3, 4 and 5 showing a burner,generally desig- .nated 34 as. being connected direct to the top of afuel tank 35, which is preferably in the form of the lamp body havinglegs 36 so that it may be supported on the floor or in the base portionof the stove 38. The burner 34, and the supply pipe 3, have portions 35and 3 respectively extending in proximity to the bottoms of the tanks 35and 5, so that practically the entire contents ofv said tanksmay beused. The burner 34 is similar to the burner shown in Fig. 2, andextending into the tank 35 is an angularly disposed air pump 39 whichpermits of the a tank being charged with air, and besides this pumpthere is a safety valve 40 and a filling opening or connection 41. Thelegs 36 of the tank 35 extend upwardly at the side walls of the tank, asbest shown in Fig. 5 and afford sockets for uprights 42 adaptedto-support an oven or, any

and when it is desired to use the burner for heating purposes, the tank35 may be-transferred to the stove 38 which has its side walls providedwith suitable openings so that the burner regulating rod 24 may protrudefrom the stove 38 to be conveniently adjusted. The safety valve 40 mayalso be regulated from without the stove 38.

Occasions or use may require the flame at the distributer 17 of theburner to be more or less mufiied and to accomplish this I provide thedistributer 17 with a centrally apertured cap 44 over which is placed aforaminous cap 45, These caps will cotiperate in retarding the flame ofthe burner so that allproducts ofv combustion maybe consumed, and toconfine the flame at the upper end of the burner and at the same timepermit of-sufiicient air reachingthe distributer 17, a cylindricalapertured guard 46 may be placed on the tank 35 about the burner 34.

There are instances when the guard 46 and Y the caps 44 and 45 willnotbe used, but when the burneris used any place where there may be acolddraft, then it is preferable to install the guard 46.

A flame deflector-"48, as shown in Fig. 9,

.may be placed on the flame'distributer 17,

particularly when the burner is used for cooking purposes and the pan,plate or other member is supported above the'burner in place of the oven43.

In placing air in the tank 5 or .35 under v pressure, the air is causedto agitate the kerosene or fuel therein to that extent that the air issaturated with kerosene and in the form of a combustible vapor which maybe ignited at the distributers of the burners and its use controlledbythe needle valve in said burners. H While in the drawings there areillustratec the preferred embodiments of myinvention, it-is to beunderstood that the structural elements are susceptible to suchvariations and V modifications as fall within the scope of the appendedclaim.

What I claim is A burner comprising a T body having a lateral liquidfuel receiving connection, said body having reduced ends, a nipple onthe upperv reduced end of said body, said body having guide grooves inthe lower reduced end thereof, a cap closing the lower reduced end ofsaid body, a needle valve in said bOClY'IHOVELblG tO and from saidnipple and having a slotted rack portion'slidable in the guide groovesof said body, a basin on the upperreduced end' of said body and retainedthereon by said nipple, a flame distributer on said nipple, a rotatablerod ex- In testimony whereof I afiix my signature in the presence of twoWitnesses.
